Question

Seed coat is not thin membranous in :

• A. Maize
• B. Coconut
• C. Groundnut
• D. Gram

Answer 1

The correct option is B Coconut

The outer protective covering of a seed. The seed coat develops from the integument of the ovule. Also called testa.

The seed coat is thick in coconut seed and thin membranous in groundnut, gram and maize seeds.

The coconut is a drupe or a fleshy fruit having hard lignified stone derived from the wall of the ovary. The seed coat is thus not thin, but membranous and tough. In maize, the seed coat is membranous and generally fused with the fruit wall. While in legumes the seedcoat is thin membranous.

So, the correct answer is "coconut".
